[Samba] Adding linux users to linux server with samba

[David.Grudek at anixter.com]

Is there a way to add the linux user to the system on the fly while you 
run smbpasswd -a and even set the password so you do not have to do two 
steps or to have adduser or useradd add a user to smb by default with the 
same password if created.  Many of the users in a small business do not 
remember to add both and then get frustrated when they can't use the 
system to find it is because they did not add users to both places.
